[Dovecot] Is there a straight forward way to associate login with imap process

[Jack Stewart]

Hi,

Is there a way to associate a user's the login (imap-login) process with 
  the user's 'imap [' process? We are trying to lock down an issue to 
make sure we full understand it. /proc and shared memory tools weren't 
particular useful.

Just for context, we are having an intermittent locking index cache 
locking issue that appears to impact only a subset of our users. The 
index files are on NFS. It may be fixed by a dovecot patch (we are at 
1.1.3), adjusting our tcp_timeout on the servers, upgrading out circa 
2000 load balancer, the type and configuration of the multiple 
simultaneous persistent clients that user is using, etc.

lslk, alert logs, strace, testing the most recent 1.1.X version, and 
file mtime is giving us some information but we want to make everything 
is covered.

Many thanks in advance.
