RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:
ldclt core dumps when using SSL with bindeach

Version-Release number of selected component (if applicable):
$ rpm -qa | grep 389
389-ds-base-libs-1.3.1.6-25.el7.x86_64
389-ds-base-1.3.1.6-25.el7.x86_64


How reproducible: Consistently

Steps to Reproduce
1. Setup SSL 
2. Import data for stress SSL testing. 
3. Run
ldclt-bin -h localhost -p 1636 -D "cn=directory manager" -w Secret123 -e "esearch,random,bindeach" -r 0 -R 1000 -b o=Stress_SSL -f "cn=monsieur XXXXXXXXXX" -v -q -n 10 -N 100 -I '-1' -W 1 -Z /etc/dirsrv/slapd-dstet/cert8.db

Actual results:
$ ldclt-bin -h localhost -p 1636 -D "cn=directory manager" -w Secret123 -e "esearch,random,bindeach" -r 0 -R 1000 -b o=Stress_SSL -f "cn=monsieur XXXXXXXXXX" -v -q -n 10 -N 100 -I '-1' -W 1 -Z /etc/dirsrv/slapd-dstet/cert8.db 
ldclt version 4.23

Segmentation fault (core dumped)

Additional info:
Sometimes there is no segfault with number of threads <= 5.
Without bindeach ldclt works as expected.

Comment 2 Noriko Hosoi 2015-01-22 01:58:00 UTC 
I could not reproduce the crash with master and 389-ds-base-1.3.3.

/usr/bin/ldclt-bin -h localhost -p 636 -D "cn=directory manager" -w password -e esearch,random,bindeach -r 0 -R 1000 -b o=Stress_SSL -f "(cn=monsieur XXXXXXXXXX)" -v -q -n 10 -N 100 -I -1 -W 1 -Z /path/to/cert8.db

ldclt[10087]: Global number times "no activity" reports: never
ldclt[10087]: Global no error occurs during this session.
ldclt[10087]: Ending at Wed Jan 21 17:56:01 2015
ldclt[10087]: Exit status 0 - No problem during execution.

But it requires to modify ldclt to support SSL version range.
I'm closing this ticket as worksforme and opening a new ticket for the range support.
