It seems like you read that as I intended, but I want to clarify I meant to say I wouldn’t feel safe assuming that this would work long term.

Not sure how else I can run a timed job if I can't use the TIMER route though.

Without digging into the actual code, I would feel safe assuming that this wouldn’t result in a memory leak or segfault after continued use.

Johan: I tried your suggested approach and (much to my surprise) it worked both for lua_exec and cache_remove_chunk. Thanks for that. Ben: I understand what you are saying for LUA. However, I think that if it's made clear that you do not have access to (or should not use) the message, the results should be predictable. It seems to work for me. My LUA function is reading in external data and doesn't make use of the message at all. Perhaps there might be a way to provide an empty message to LUA if it's invoked in TIMER routes to avoid possible problems? LUA and Python offer powerful extendablity to OpenSIPS, so it seems to me to be a bit of a shame to limit their use at startup or in timers if all that's needed is a tweak - or even just a warning in the documentation. As for the "cache_remove_chunk" - it's less clear why TIMER couldn't run this in a straightforward way as it's not dependent on the current message as far as I understand it. If anybody wants to try doing this - here's an example that worked for me in OpenSIPS 3.1... timer_route[refreshNodes, 30] { route(remove_chunk); route(cache_reload); } route[remove_chunk] { cache_remove_chunk("validNodes", "*"); } route[cache_reload] { lua_exec("getValidNodes"); for ($var(node) in $(avp(validNodes)[*])) { cache_store("local:validNodes", "$var(node)", "true"); } } On Thu, 3 Dec 2020 at 14:20, Ben Newlin <ben.new...@genesys.com<mailto:ben.new...@genesys.com>> wrote: I wouldn’t recommend trying to bypass the restriction in this way. Both the lua and python exec modules were designed to operate on a SIP message, which is why they can only be called from routes that process messages. Calling it from time_route where there is no message, even if you could get it to work, could have unexpected and unpleasant results. >From LUA module doc for lua_exec: “Calls a Lua function with passing it the >current SIP message” [1].
