Panic: file istream-seekable.c: line 226
Hi,
I have a lot of Panic in my logs. They happen almost every day and never on the same user. When it happens, the mail is not distributed (it's always lda). I discovered it because my Sympa server had a lot of users in error. The last error (below) was a local user sending a mail to 10 users : 3 of them never get the email.
I've looked into my logs and discovered it started after the upgrade from 2.2.27 to 2.3.4 in february. I'm on Debian.
This week, I installed the dovecot repo and upgraded to the very last and same thing. The error below happened after the latest upgrade.
An example :
