Bug#383457: nscd dies with SIGABRT with an enabled hosts cache
Package: nscd
Version: 2.3.6-19
Severity: normal
nscd dies on the first reload of a hosts cache entry. Disabling the hosts cache
in nscd.conf works around the problem. Relevant parts of a strace output:
# strace nscd --debug
...
epoll_wait(11, {{EPOLLRDNORM, {u32=12, u64=12}}}, 100, 29976) = 1
epoll_ctl(11, EPOLL_CTL_DEL, 12, {0, {u32=0, u64=0}}) = 0
futex(0x55555566c524, FUTEX_WAKE, 1) = 1

I'm using nscd to cache user/group from the ldap server - but turning off the
ldap service in nssswitch.conf didn't help in any way.
If there's something else I can provide or test, I'd be glad to do so.
