I've upgraded dovecot from 2.2.18 to 2.2.30.2 but errors are still present
posta2:/var/core # dovecot --version 2.2.30.2 (c0c463e)bye
Errors appear only with dovecot-lda process so I tend to exsclude
disks or ocfs failure
Is there someone who can help me?
Best regards
Thanks

I've upgraded dovecot from 2.2.18 to 2.2.30.2 but errors are still present
posta2:/var/core # dovecot --version 2.2.30.2 (c0c463e)bye
Errors appear only with dovecot-lda process so I tend to exsclude disks or ocfs failure
Is there someone who can help me?
Hello
To us it looks like the crash is happening inside your operating systems kernel. That would also be the primary target when looking for a resolution. There might not be anything that can be done by Dovecot.
br, Teemu
Best regards
Thanks
