I keep running into the following error when my site is sending out emails:
unknown exception condition
All of the information that I can find online says that this error could be due to a bug with CF4.5, but it was fixed with CF4.51. Since we are on 5, I am not sure what the cause of the problem could be.
If I reboot the server, all the emails flow as they should. They continue to work for a little bit after the reboot but then the error comes back - if I reboot the server again, the emails start working again and so on...
Based on some other tips, here is what we have checked so far:
1. Permissions on all of the mail folders (the CF application service is running on local system account)
2. Hard drive space - free space is around 12 gigs
3. Spool and Undeliverable folders do not have any files that are 0 Kb
4. Spool and Undeliverable folders do not have 65,535 files in them
Any help would be greatly appreciated.
