Hello, I use the zlib and imap_zlib plugins on FreeBSD. As of 2.3.0, my logs are producing these errors every so often, but AFAICT the messages themselves aren't getting corrupted.

Hello everybody, i tried to debug imap sessions with the rawlog feature and rawlog creates files but when i try to dump them doveadm tells me [...] Error: zlib.read((file)): unexpected EOF at [...]. I looked at syslog files and i see, that rawlog gets terminated with a segfault, e.g.: segfault at 10 ip 00007ff6da362596 sp 00007fffe725a080 error 4 in libdovecot.so.0.0.0[7ff6da2a4000+122000] Is

That user switched to bz2 compression what worked for him. the answer was : > are you on

Hi. I've made a new attempt at build Dovecot. The build and then install processes appeared to work find. Then when I try to run Dovecot it reports the error: /share/MD0_DATA/optware/opt/sbin/dovecot: error while loading shared libraries: libdovecot.so.0: cannot open shared object file: No such file or directory To get a better idea of what's going on, I added

Hello Pascal, I've just tested rc6 and get almost the same results. imap still crashes, but Horde still works. I forgot to mention that this is on FreeBSD 8 using gcc 4.6 and LTO. And contrary to what I said in my initial email, it doesn't seem to be ACL plugin related. imap crashes even if it's not in the plugins list. Here is the backtrace: # gdb /usr/libexec/dovecot/imap
