I do not know if this is a FreeBSD issue or a KDE issue. The problem occurred after I updated KDE, but I had also updated FreeBSD at about the same time. I have filed a KDE bug too: http://bugs.kde.org/show_bug.cgi?id=122457 Here is a gdb backtrace from the wedged process: (gdb) info thread * 3 LWP 100142 0x294417dd in read () from /lib/libc.so.6 2 Thread 0x805d000 (runnable) 0x294417df in read () from /lib/libc.so.6 1 Thread 0x833fa00 (LWP 100139) 0x2938446b in pthread_testcancel () from /usr/lib/libpthread.so.2 (gdb) thread 2 [Switching to thread 2 (Thread 0x805d000 (runnable))]#0 0x294417df in read () from /lib/libc.so.6 (gdb) bt #0 0x294417df in read () from /lib/libc.so.6 #1 0x2936d19a in read () from /usr/lib/libpthread.so.2 #2 0x297409d1 in BIO_sock_should_retry () from /lib/libcrypto.so.4 #3 0x297a93c3 in BIO_read () from /lib/libcrypto.so.4 #4 0x298c8cf9 in SSL_set_msg_callback () from /usr/lib/libssl.so #5 0x298c9922 in ssl3_read_bytes () from /usr/lib/libssl.so #6 0x298cb035 in ssl3_renegotiate_check () from /usr/lib/libssl.so #7 0x298c652e in SSL_read () from /usr/lib/libssl.so #8 0x2821310c in KOpenSSLProxy::SSL_read (this=0x8363160, ssl=0x83b4400, buf=0xbfbfd1b0, num=4095) at kopenssl.cc:661 #9 0x28203317 in KSSL::read (this=0x8347a40, buf=0xbfbfd1b0, len=4095) at kssl.cc:485 #10 0x282677bb in KIO::TCPSlaveBase::read (this=0x8349000, data=0xbfbfd1b0, len=4095) at tcpslavebase.cpp:174 #11 0x296bd321 in POP3Protocol::myRead () from /usr/local/lib/kde3/kio_pop3.so #12 0x296c2727 in POP3Protocol::get () from /usr/local/lib/kde3/kio_pop3.so #13 0x2826b1a1 in KIO::SlaveBase::dispatch (this=0x8349000, command=67, data=@0xbfbfe320) at slavebase.cpp:1020 #14 0x28269d05 in KIO::SlaveBase::dispatchLoop (this=0x8349000) at slavebase.cpp:290 #15 0x296bcfe0 in kdemain () from /usr/local/lib/kde3/kio_pop3.so #16 0x0804f21d in launch (argc=4, _name=0x8345404 "kio_pop3", args=0x8345486 "", cwd=0x0, envc=0, envs=0x834548a "", reset_env=false, tty=0x0, avoid_loops=96, startup_id_str=0x805189c "0") at kinit.cpp:639 #17 0x0804f8ca in handle_launcher_request (sock=8) at kinit.cpp:1203 #18 0x0804fe6c in handle_requests (waitForPid=0) at kinit.cpp:1406 #19 0x08050465 in main (argc=2, argv=0xbfbfe980, envp=0xbfbfe98c) at kinit.cpp:1850 >How-To-Repeat: I cannot get the problem to occur on command.
