Max instable

Hi there,

I’ve been making a patch for a play, and I find it to be very instable (around a few crashes per hour).

I know that this question is asked a few times before, but the answers didn’t give me a clear direction for what I could do. Time is running out for me and I don’t seem to find a solution myself (sad face). It would be great if someone could point me in the right direction (puppy face).

purpose of the patch:
It’s a 5 layered video sequencer for black-white video’s. Output is for 2 projectors. Input is sensor-data to manipulate the video’s (step through the video, start video, go to next video…)

main structure of the patch:
1 ‘channel’ bpatcher with 2 slab-chains that is used 5 times in the main patch. It’s connected to a pattr system with unique names so I can address the objects inside each channel.
A general render engine with 2 windows
A sensor-subpatch

when the crashes occur:
sometimes when I’m moving an object, sometimes when I go to the next pattr preset, sometimes when I’m not touching the computer at all. The crashes are not reproducible and in rare cases there even is no crash log. I don’t use third party externals.

curiosities I found in the console:
every start-up it prints this:
Max(3278,0xa080f540) malloc: *** error for object 0x19e71000: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug

sometimes I can find lots of these:
*** Assertion failure in -[NSEvent deviceDeltaX], /SourceCache/AppKit/AppKit-1038.36/AppKit.subproj/NSEvent.m:2323

sometimes I can find one of these:
_RemoveTimeTask(), the current time manager task 0x1e94358c being removed is also currently executing its tmAddr routine, so unexpected things may result ( Radar #4555679 ).

I’m using max 5 and 6 (6 seems more crash-sensitive than 5)

I’ll attach the patch (although it’s pretty much undocumented, sorry for that!).
Regular workflow:
1. open folder with videos at the upper left corner of the screen.
2. play with the movies in the channels
3. store and recall presets

Also attached: the last 3 crash logs

thanks a lot!

Just to be complete:
sometimes it crashes pretty soon, other times it crashes after a while. There doesn’t seem to be any predictability.

Update: I trashed the pattr system, throwed out all things that I didn’t really need and temporarily disabled the sensor-part. Now it’s stable.
