Hello colleagues,
On March 22nd we updated the 389-ds-base.x86_64 and 389-ds-base-libs.x86_64 packages on
our eight RHEL 7.9 production servers from version 1.3.10.2-17.el7_9 to version
1.3.11.1-1.el7_9. We also updated the kernel from kernel 3.10.0-1160.80.1.el7.x86_64 to
kernel-3.10.0-1160.88.1.el7.x86_64 during the same update.
Approximately 12 days later, on April 3rd, all the hosts started exhibiting memory growth
issues whereby the “slapd” process was using over 90% of the available system memory of
32GB, which was NOT happening for a couple of years prior to applying any of the available
package updates on the systems.
Two of the eight hosts act as Primaries (formerly referred to as masters), while 6 of the
hosts act as read-only replicas. Three of the read-only replicas are used by our
authorization system while the other three read-only replicas are used by customer-based
applications.
Currently we use system controls to restrict the memory usage.
My question is whether this is something that other users also experience, and what is the
recommended way to stabilize the DS servers in this type of situation?
Thanks,
- Alex
