Hi All, I have had reports of problems with the -R option on OSX 10.6.4. Just tested it myself and found this odd result: When I run this "dtruss -f path/to/rsync -aHAXNR --fileflags --force-change --protect-decmpfs --stats -v /Users/astrid/Documents/main.m /Users/astrid/Desktop/rrr it produces the expected results with the relative folder paths in place /Users/astrid/Desktop/rrr/Users/astrid/Desktop/main.m but copying file from Desk...

We''re running a Solaris 10 container, with an Oracle 9.2.0.4 database - every 5-10 min, an Oracle process shoots up (using 20% + CPU) and then goes down in CPU %, doing a [i]pollsys [/i](see it via dtruss). I tried using some of the trace scripts in the Dtracetoolkit to see what the process is doing, but without any luck - also tried with the following, but dtrace process goes up to 30% CPU, then I kill it: #!/usr/sbin/dtrace -s #pragma D option flowindent pid14344::select:entry { self-&g...

Hi, I''m a nub in dtrace, could you please help me to find the mistake? I need to implement the logic: - if PID and TID are defined, fire the probe for the particular thread of particular process; - if only PID is defined, fire the probe for the process including all threads. The predicat [i]syscall:::entry / (pid == PID && tid == TID )[/i] / works ok and return syscall for

Hi, y'all, long-time Mac OS X Server user Bill here with a thorny question for the mailing list since nobody at discussions.apple.com can quite put their finger on the answer. While well-aquainted with other aspects of Server, Dovecot is a bit of a mystery still to me. So here it goes: Background I'm struggling to migrate from MacOS X 10.6 to 10.9. I tried twice using the "live

I tried some of the scripts in the toolkit (opensnoop, execsnoop, dtruss), and I keep seeing errors like this: dtrace: error on enabled probe ID 3 (ID 113: syscall::exece:return): invalid kernel access in action #5 at DIF offset 0 Anyone know what could be the problem?

The R process itself uses almost no CPU. Unfortunately, I do not have any experience with neither "Sock_listen" nor "dtruss". Is there an example somewhere available?

Hello, With the same basic configs as in my previous messages, I tried with the maildir format instead of the mbox format. That is, in both cases ("virtual" uids/gids vs a single "real" uid/gid), doveconf -n shows: mail_location = maildir:~/maildir instead of: mail_location = mbox:~/mboxes:INBOX=~/mboxes/inbox Here too, with "virtual" uids/gids, connections thru

Now zpool is healty again, but perfomance realy s*cks. Accessing older data takes way to much time. Doing "dtruss -a find ." in a zfs filesystem on this b77 server is extremely slow, while it is fast in our backup location were we are still using opensolaris b57 and zpool version 3. Writing new data seems normal, we don''t see huge issues here. The real problem is do ls, rm or find in filesystem...

Hi all, The call parallel::makeCluster(1L) hangs infinitely on my MacOS machine which seems to be already reported by some people (e.g., https://stat.ethz.ch/pipermail/r-devel/2018-February/075565.html). However, the solutions posted on SO, GH or R-devel do not work in my case. So far, I unsuccessfully tested ? 1. Couple of reboots 2. Adding 192.0.0.1 to /etc/hosts 3. Using R.app

...I could only get rid of it with a "kill -9 <pid>". The same happened when selecting a newly created mailbox on any of the other (otherwise functioning) accounts, so the problem had nothing to do with the new account, but rather with the fact, that it's INBOX was empty. Using dtruss and gdb I found out, that the dovecot process was trying to obtain a GUID and in the course of doing so invoked gethostbyname(), which intern caused a lot of "mach message" handling and somewhere, deep down there, the process was stuck. Well, that led my to believe, that there was someth...

Comparing to the 'good' setup the pause at the same place in the communication is less than 1 ms ! So why this delay? Where/how shall I continue my debugging? - Run dtruss/dtrace scripts on the server? - Get dovecot to output more debug info (I guess it's doing it's best so no problems will be seen there?)? Are there any dovecot configurations that can be altered to workaround [what I think is a limitation in Outlook's IMAP implementation]? The current d...

SELECTing a mailbox has nothing to do with FETCHing messages, so above does not make much sense. I don't know dovecot's code, but I

...duce on our system indeed we could debug, if not there could at least be more directed advice on how to debug on your side. What I'd do myself if I could reproduce on my system would be instrument R around Sock_listen in internet module to see exactly what has failed with which error. Maybe dtruss would help too, but instrumenting may be easier. The earlier problem you mention has never been diagnosed (it was only intermittent on the reporter's machine, we could not reproduce on our systems, and despite a lot of effort on our side and on the reporter's, we could not reliably dia...
