Trigger message limit?

Am facing problem in trigger.
Messages are getting pilled up like anything because of huge transactions
because of this we have suspended few unwanted triggeres for time being to improve other performance of important triggers.
Now the message in the trigger Queue is more than 15,000.
Can any one let me know how many days i can susupend a trigger with messages?

It depends on what version of webMethods Integration Server you are using and what you have set on your trigger settings for the a particular trigger. Older versions of webMethds Integration Server did not persist the suspend trigger, so if you restarted the IS server, things started processing or possibly worse lost if set to volatile.

If you have it set for deliver until successful, Guaranteed for the document (and with Discard = false) and you are at the correct version then you should be okay.
