Actually its not tcp_wrappers.
When I start importing , I get 723 messeages like the ones below:
16677 22:43:37.184060 rt_sigaction(SIGPIPE, {SIG_IGN}, NULL, 8) = 0
16677 22:43:37.184221 mmap2(NULL, 10489856, PROT_READ|PROT_WRITE,
MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = -1 ENOMEM (Cannot allocate memory)
16677 22:43:37.184350 time([1113011017]) = 1113011017
16677 22:43:37.184442 rt_sigaction(SIGPIPE, {0x585aa0, [], SA_RESTORER,
0x4f4f48}, {SIG_IGN}, 8) = 0
16677 22:43:37.184540 send(5, "<19>Apr 8 22:43:37 cyrus/mupdat"..., 89,
0) = 89
16677 22:43:37.184634 rt_sigaction(SIGPIPE, {SIG_IGN}, NULL, 8) = 0
16677 22:43:37.184782 mmap2(NULL, 10489856, PROT_READ|PROT_WRITE,
MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = -1 ENOMEM (Cannot allocate memory)
723 mmap2 failures with ENOMEM
and on my cyrus log I get this
cyrus-fe1 cyrus/mupdate[16671]: could not start a new worker thread (not
fatal)
cyrus-fe1 last message repeated 722 times
Im still trying to reproduce the mmap failure inside map_refresh, but
debuging with strace -f makes cyrus too slow
