Fixed In:

Opened: Jan 12, 2016 Severity: 1-Blocking
PEM was incorrectly doubling the value of the sysdb var tmm.pem.spm.maxsessionlimit.
You will notice that the maximum number of sessions supported by PEM is now half of what it used to be.
This will impact only those users that have modified the sysdb var tmm.pem.spm.maxsessionlimit prior to version 12.1.0 and then upgraded to 12.1.0 or beyond.
None
We now honor the value specified in the sysdb var tmm.pem.spm.maxsessionlimit. If you have modified the value for this sysdb var prior to 12.1.0, you will need to fix this value in your config. The sysdb should now be set to the desired value(instead of half of the desired value). If you use BIG-IP with htsplit disabled, it is recommended that you reduce this value, since there are more tmms with htsplit disabled.
