Preface: I use pidgin on network scenario under vpn, and so it is easy that connection go down. So, when this happens and pidgin try to do a new connection a SIGPIPE is handled or (still with version 2.2.1) cpu go to 100%. Duo instability of pidgin i run pidgin always under gdb debugger and so hereinafter i insert backtrace of error: 1. Sometimes this error is handled: Program received signal SIGPIPE, Broken pipe. 0x00002b138b94dcc0 in write () from /lib/libpthread.so.0 (gdb) bt #0 0x00002b138b94dcc0 in write () from /lib/libpthread.so.0 #1 0x00002b1398e1ed31 in msn_servconn_write () from /usr/lib64/purple-2/libmsn.so #2 0x00002b1398e12608 in msn_cmdproc_send_quick () from /usr/lib64/purple-2/libmsn.so #3 0x00002b1398e1cc58 in msn_notification_close () from /usr/lib64/purple-2/libmsn.so #4 0x00002b1398e1f951 in msn_session_set_error () from /usr/lib64/purple-2/libmsn.so #5 0x00002b1398e1ec7e in msn_servconn_got_error () from /usr/lib64/purple-2/libmsn.so #6 0x00002b1398e1ef93 in ??

Reproducible: Sometimes Steps to Reproduce: 1. Often when there are problems with connectivity 2. 3. Actual Results: Now, Pidgin isn't so usable.
