Every couple of days (I don't really keep track of how often), Thunderbird stops checking my mail. I'm running WinXP Home on a compaq presario 2100, 1.6GHz Celetron, 192MB RAM. I'm using POP3, server has Qpopper 4.0.3. When I check the server logs, I get this:
Jul 18 22:18:02 neutron popper[9764]: I/O error flushing output to client chad at hostname.domain.com [xxx.xxx.xxx.xxx]: Operation not permitted (1)
Closing Thunderbird, and starting it back up, fixes the problem. I haven't found any other posts about this on these forums, or in Bugzilla. Wanted to get some feedback, see if anyone else has come across this.
