Failed to read line: No such file or directory

crankshaft

One of our users throws a No such file or directory error each time they login, this only happens with this user.

I have set the gateway logging to level 5 (max) however the error message does not provide much info as to the cause / solution.

Mar  9 16:44:35 kopano kopano-gateway[980]: IMAP Login from [[::ffff:xx.156.xx.67]:38438] for user "xxxx"
Mar  9 16:44:35 kopano kopano-gateway[980]: Failed to read line: No such file or directory
Mar  9 16:44:35 kopano kopano-gateway[980]: Client [::ffff:xxx.156.ccc.67]:38438 thread exiting

We use IMAP and the user has tried to fix this error by using the ‘Repair’ option in the mail client (Thunderbird) however the repair process appears to hang, probably because the thread exited prematurely.

How can I find the cause of this and fix it ?

How can I find the cause of this

gateway.cfg: Set log_level to debug(6) and repeat.

Thanks for helping.

The logs are now immense, but at the end of the log, there is still no indication as to the reason:

This possibly happens here: gateway.cpp.
Sounds like something serverside closed the receiving filedescriptor or SSLcontext.
What is your gateway’s process_model?

@umgfoin - Thanks for helping.

I have no override for this so it is the default fork

@crankshaft just wondering…
is this an IPv6 Client? and if yes, can you test this user on a IPV4 connection then.
