Disconnect reconnect issue

[Dave Haskel]

I'm having this issue while using Pidgin on a server running Openfire
Spark. Everything works, but other users complain that I disconnect and
reconnect randomly. I don't notice this behavior at all, but they say they
see this in their chat windows:

*** Dave Haskel is online at 10:17 AM
*** Dave Haskel is online at 10:19 AM

I have disabled all of the plugins except for Autoaccept, History, Expand
URLS, and Psychic mode

Any ideas?
