Although with a slapd without debug symbols it works ok, there's an assert
that fails in slapd_clr_write method, ("assert( SLAP_SOCK_IS_ACTIVE( s ))"):
(gdb) bt

Hello,<br>
<br>
I still reproduce this problem with 2.4.17-prerelease. I have a client<br>
that request a lof of operations at the same time through a connection.<br>
The slapd seems to overload and finally close the connection sending a<br>
reset to the client and when this happens the connection hungs eating the<b=
r>
CPU, blocked in the pthread_cond_wait in send_ldap_ber function at the<br>
same point of the first trace sent in this report.<br>

This should now really be fixed in HEAD and RE24. =C2=A0Please test.</block=
