Re: frequent slapd freeze with openldap 2.4.13

And gdb shows it waiting in __kernel_vsyscall (gdb) bt #0 0xffffe410 in __kernel_vsyscall () #1 0xb7d385c6 in pthread_join () from /lib/i686/libpthread.so.0 #2 0xb7f23d3f in ldap_pvt_thread_join () from /usr/lib/libldap_r-2.4.so.2 #3 0x0806e1b4 in slapd_daemon () #4 0x0805a507 in main () In both case, I think the lack of relevant information is caused by the multithreading nature of slapd, I don't know how to access the exact thread where the problem occurs.
