OK, I just recreated the situation. The imapd's all hang in a select()-call:

[root at lvr1 cyrus]# strace -p 19411
select(1, [0], NULL, NULL, {1729, 930000} <unfinished ...>
[root at lvr1 cyrus]# strace -p 19417
select(1, [0], NULL, NULL, {1716, 430000} <unfinished ...>

gdb backtraces look like this:

0x402e3bee in __select () from /lib/i686/libc.so.6
(gdb) bt
#0  0x402e3bee in __select () from /lib/i686/libc.so.6
#1  0x0811a994 in __DTOR_END__ ()
#2  0x0808410c in getword ()
#3  0x0804f37e in cmdloop ()
#4  0x0804efb2 in service_main ()
#5  0x0804d6a1 in main ()
#6  0x40218687 in __libc_start_main (main=0x804cd60 <main>, argc=1, 
ubp_av=0xbffecdf4,
    init=0x804b9e4 <_init>, fini=0x8098120 <_fini>, rtld_fini=0x4000dcd4 
<_dl_fini>,
    stack_end=0xbffecdec) at ../sysdeps/generic/libc-start.c:129

They seem to be the same for all of the processes ...

This is still cyrus-imapd 2.1.11. master still responds to POP requests, so 
I don't think there's anything wrong with it.

Does this help in any way?
