TCL error from APM Policy

I have a tweaked APM policy for accessing 2 citrix environments and we're getting strange issues where non-IE browsers are failing to launch a Desktop and are outputting the following error into the LTM log:

TCL error: /Common/_sys_APM_Citrix_IcaPatcher  - can't read "tmm_apm_ica_addr": no such variable while executing "if { $tmm_apm_ica_addr starts_with ";" } { log -noname accesscontrol.local1.debug "01490000:7: ICA Patcher: STA Servers = '[ACCESS::sessio..."

The strange this is, I cannot find any reference to this _sys_APM_Citrix_IcaPatcher iRule anywhere in the conf files.

Has anyone seen this sort of thing before and possibly shed some light on a solution?

Many thanks!

    Do you have _sys_APM_Citrix_IcaPatcher irule created in your irule list ??

     

  • No it doesn't exist on the F5's which is whats confusing. If it was part of the iApp I'd have expected it to have been there. Unless it is in a different conf file?

     

  • Nothing comes up apart from errors in log files. I think the problem is related to old iApp with a new Citrix. I've build a new APM policy on the F5 and its all working now without issue.

     

    Thanks all for your help.
