Segfault vdelivermail with vpopmail 5.4.32 - Sat, Jan 8, 2011
This had me stumped for a while while installing vpopmail5.4.32 (currently at time of writing is the stable version) on a fresh amd_64 debian lenny machine.
Random segfaults with vdelivermail that look like this:
vdelivermail: segfault at 0 ip 00007f4164e470b0 sp 00007fff1a370528 error 4 in libc-2.7.so[7f4164dcc000+14a000]
Restart vusaged and your problems should be fixed, at least it worked for me. Why this bug managed to get into a stable version I have no idea, but hopefully this will save you some headaches should this be a production machine.
