[vchkpw] Issues with authentication error: Input/output error

[Mike Bloom]

Hello,

I'm getting seemingly random errors authentication errors from courier 
using authmodulelist="authvchkpw" to authenticate my pop and imap sessions.

I've experimented with varying the number of daemons used to 
authenticate, but I'm looking for anyone with real life experience on 
tweaking authdaemonrc in coordination with the authvchkpw module for 
extra debugging info or a sanity check for my current requirements.

Thanks.

M
