  • Dear All,

      Name           BIG-IP 1600

    based on open TAC and F5 principal, they said

    "In the iHealth Diagnostics section you'll find that the memory issues you are experiencing are related to the following two SOL articles:

    SOL15036 TMM may experience false port exhaustion and produce a core file https://support.f5.com/kb/en-us/solutions/public/15000/000/sol15036.html

    SOL15010: TMM may stop responding due to a memory leak caused by the source address translation subsystem https://support.f5.com/kb/en-us/solutions/public/15000/000/sol15010.html

    The good news is that both of them have been fixed in newer builds and you simply need to apply the patch."

    what my question is.
    1. do you all have the MOP how to upgrade/apply the patch in F5, step by step guide and MOP Template, my box is HA Cluster
    2. what is the impact if we not upgrade/apply the patch?

      ill just repeat my previous comment, search dev central, many people have asked about upgrade notes, all the information is there you just have to combine it. if you dont upgrade / apply you are stuck with the bug that was causing you issues in the first place. high memory can get higher and higher until the box crashes. at some point support on that version will also stop. so upgrading once in a while is a wise thing to do. if you don't feel comfortable the first time you can also look into approaching your f5 partner for help.
