...opening mailboxes. Total time to open the box was about 1 minute. Upon truss'ing the imap process during an open, I saw the trace quoted below at the end of the email. As you can see, for each "FETCH" line of response, we were seeing dovecot do a ton of work-- mmaping anon, lots of munmaps(), etc. -- mmap() and munmap() are not free. The stack trace of at least one of the munmaps is captured below, as well-- deep inside of the mail caching code. Then, I moved aside the user's .imap directory, assuming that forcing dovecot to rebuild its indices and caches could help-- and sure...

Hello, After update dovecot to version 2.3.x, LMTP stopped to receive big messages ( > 45 MB ). Messages are being sent to dovecot LMTP by postfix. If I change this email to another server with dovecot 2.2.x the same message are delivered immediately. Log with mail_debug = yes: Apr? 4 13:36:13 mailsrv01 dovecot: lmtp(190031): Debug: none: root=, index=, indexpvt=, control=, inbox=, alt=

I observed several long running dovecot/lmtp processes hogging the CPU. I then strace'd them (strace -c -p 6375) and found them munmap()-ing a lot: % time seconds usecs/call calls errors syscall ------ ----------- ----------- --------- --------- ---------------- 97.18 19.592537 1878 10430 munmap 2.28 0.458984 36 12696 epoll_ctl

Hi, Header says: /* * Unmaps the @count pages starting at @start_address, which were mapped by a * call to xc_gntshr_share_*. Never logs. */ int xc_gntshr_munmap(xc_gntshr *xcg, void *start_address, uint32_t count); But implementation calls: static int linux_gntshr_munmap(xc_gntshr *xcg, xc_osdep_handle h, void *start_address, uint32_t count) { return

I'm testing both sunfreeware and official sun (sfw) samba on Solaris 10. For some reason since yesterday, the smbd process just "hangs" at the start. No log is generated on server side Where smbd is started, I can't find any open port on 139 or 145 My OS is Solaris 10 # uname -a SunOS labo2 5.10 Generic_142900-13 sun4v sparc SUNW,SPARC-Enterprise-T5120 #

Hi, i'm running dovecot on a SMP sparc 32bit server with solaris 8(latest patch installed). Dovecot with ssl. Postfix+imap+maildrop . Dovecot work fine with every email and folders delivered by maildrop, but now i'm trying to move all my local folders (i'm using mutt and i'm storing my emails locally on my pc) to the imap server . The upload of an entire 12000 mails folders

Hi! Just updated to 1.0 rc15, but the problem remains. I think it could be client-dependent to some extent. I have only IMAPS access and Maildir. I have one mailbox which contains some 10,200 mails. That mailbox takes forever (have waited 30 minutes and then aborted) to open with Thunderbird 1.5.0.7. Other mailboxes (like dovecot :-), only 6984 mails) opens quickly. When Thunderbird tries to

Hi Xen folks! I''ve faced with one strange thing in ARM version of Xen: when I use xc_map_foreign_bulk() to map some memory from domU to dom0, after unmap() for previous returned address - memory is not freed at all. Let''s look at call stack: xc_map_foreign() -> linux_privcmd_map_foreign_bulk() -> { addr = mmap(fd); ioctl(fd, IOCTL_PRIVCMD_MMAPBATCH_V2 );

This is with last night''s Xen snapshot (apr 24th), on kernel 2.6.12-rc3 - but the mess is so horrid that I''m not quite sure how to fix it... This oops prevents xen from starting xenU domains. Basically xend does the following: 1) mmap /proc/xen/privcmd 2) call an ioctl to populate the mmap 3) munmap the mapping created in (1) During the munmap, the dom0 kernel oopses, as

Hi, I am having a problem where puppetd won''t start on one of my RHEL 5 machines with the --listen option enabled. 0.23.2 seems to run fine but 0.24.0 dies leaving the pid file still there. I installed puppet using the latest gem from reductive labs. It works fine on what is meant to be an identical system. I tried running strace and it seems to exit after trying to write to a bad

Heres is the output of truss /usr/local/samba/bin/nmbd execve("/usr/local/samba/bin/nmbd", 0xEFFFFCA0, 0xEFFFFCAC) argc = 2 open("/dev/zero", O_RDONLY) = 3 mmap(0x00000000, 8192, PROT_READ|PROT_WRITE|PROT_EXEC, MAP_PRIVATE, 3, 0) = 0xEF7C0000 open("/usr/lib/libsocket.so.1", O_RDONLY) = 4 fstat(4, 0xEFFFF83C) = 0

Perhaps I can ask a slightly different question? Is there some kind of test I can do on a hung process so I can determine whether it's active or not, in a script? The output of strace is below but it doesn't mean much to me I'm afraid. Is there a straight forward difference between strace for a "real" connection and one of my hung ones that I can use to manually kill them?

I'm getting orphaned processes on our mail servers. Some machines has processes hanging around from a week ago. I'm running the current stable of dovecot 2.1.15, but the problem has been happening for a while now. I thought it would be good to report the issue. I ran an strace on one of them and this is the output: Process 21370 attached - interrupt to quit

Hi all! It seems the current ext3 code has some problems; my machine is running 2.4.6-ac1 with ext3-0.9 patches on top of it. This afternoon, I was doing some testing of a little piece of code on my machine, and I was able to crash it. What this program does is, in effect something like (pseudo-code) for(i=0; i<100; i++) { fd=creat file-i truncate fd, 50M mmap fd close fd fill the
