This issue has been fixed in these releases. Web Application Firewall (WAF) configuration containing a sideband iRule configuration can also result in high memory utilization. If you are using WAF, be aware that high memory utilization can result in high CPU utilization and increased session timeout rates. This issue has been fixed in these releases. Memory issues can also occur with TMM if a high number of connections are present in the server pool. This issue has been fixed in these releases. TMM memory issues can be mitigated by the use of reserved pools and configuring sufficient connections per pool. This issue has been fixed in these releases. Be aware that reserved pools do not provide load balancing and may result in high CPU utilization. This issue has been fixed in these releases.
