Hello all,
I have noticed that in the OpenDNSSEC trunk, ods-signerd accumulates a
connection to /var/run/opendnssec/engine.sock each time a command is issued
to the signer. Eventually, ods-signerd will stop operating when the open
file limit is reached.
strace reveals ods-signerd is doing the following once it hits 1024 open
files:
...
[pid 4021] select(6, [5], NULL, NULL, NULL) = 1 (in [5])
[pid 4021] accept(5, 0x7f1109b1ce20, [110]) = -1 EMFILE (Too many open
files)
[pid 4021] select(6, [5], NULL, NULL, NULL) = 1 (in [5])
[pid 4021] accept(5, 0x7f1109b1ce20, [110]) = -1 EMFILE (Too many open
files)
...
It looks like in ./src/daemon/cmdhandler.c, close is never called on the
socket that is opened by cmdhandler_start(). The following patch seems to
resolve the problem for me:
--- cmdhandler.c (revision 4141)
+++ cmdhandler.c (working copy)
@@ -857,6 +857,8 @@
void
cmdhandler_cleanup(cmdhandler_type* cmdhandler)
{
+ if (cmdhandler->client_fd > 0)
+ close(cmdhandler->client_fd);
if (cmdhandler) {
se_free((void*)cmdhandler);
} else {
Cheers,
James Dempsey
