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.
Panic: file ostream-zlib.c: line 36 (o_stream_zlib_close): assertion failed: (zstream->ostream.finished || zstream->ostream.ostream.stream_errno != 0) Fatal: master: service(imap): child 80128 killed with signal 6 (core not dumped - set service imap { drop_priv_before_exec=yes }) Panic: file ostream-zlib.c: line 36 (o_stream_zlib_close): assertion failed: (zstream->ostream.finished || zstream->ostream.ostream.stream_errno != 0) Fatal: master: service(imap): child 80266 killed with signal 6 (core not dumped - set service imap { drop_priv_before_exec=yes })
I'm also seeing these errors, but I actually use gz compression. I'm running 2.3.0 on Arch Linux. Config and logs are below.
Do you need any more information or can you reproduce this?
