I have Vpopmail 5.4.0 installed on a FreeBSD 4.9 system.
We experienced a situation with very heaver load averages (sometimes > 30) and determined that vdelivermail seemed to be taking far too long to process mail delivery.
I ran truss on several of the vdelivermail processes and discovered that vdelivermal was doing a stat on every directory in the recipients domain, evidently for quota purposes. However, no quotas are installed on the system. vlimits.default is using default and every user also has NOQUOTA set.
Any ideas as to what could be causing this?
