[Dovecot] Strange issue in NFS

[Alex Baule]

Hi Timo...

It's happens some strange issue with my maildir using NFS.

If i use a Local Hard disk, i don't get any of this messages about memory
error.

returned error 83 (Out of memory (vsz_limit=256 MB, you may need to increase
it))


I Try to increase the vsz_limit in imap to 2048 MB, and i try too , put 0 MB
(like no limit) and i still get this same error (only change the vsz_limit
to my write limit).

What is most used "Shared Disk" in Dovecot ?

Tks Timo !!
