Export audio problems

When exporting big projects (40-50 tracks with lots of EW play sounds) it's almost impossible to get the result sound as in SONAR. EW Spaces is not rendering and some sounds dissappear while some extra sounds appear. And some stereo glitches appear as well (only left speaker for example). Problems both with and without "fast bounce", sometimes it is even worse without.
Any setting to make exporting better? I have almost 20 ms buffer size to be able to play everything with effects.

    Raise your buffers even further. 20ms is way too small

    I set my midi buffer at 1,200 as example if that is what you are referring to. . 
    Audio buffers for mixing most will crank those up to a middle ground like 256ms.

    20ms (not samples) is roughly a 1024 sample AUDIO buffer. Higher buffer (2048) may help but you are then putting stress on your drives since you are pulling samples (EW).

    First, check your "prepare using ms buffer" for MIDI (defaults to 250) and jack that up to 1000 or 1250. See if that helps, and this is a MIDI parameter. Also check your disk I/O buffers (both read and write) and set those to 512 (default is 256 IIRC). My system freaked on a large project once and that 512 cured it.

    Last resort (ONLY)... If that still doesn't cut it, save the project with a new name and try bouncing all the tracks to new tracks, then delete the originals (BE SURE TO SAVE THE PROJECT WITH A NEW NAME FIRST). This will turn an export into a wav file mix only (as simple as it gets... very little stress to your system). A 1024 sample audio buffer should suffice.

    I have an old interface (Saffire 6 USB) and 1024 samples (23,2 ms) audio buffer is maximum.
    But... I must have missed the thing with MIDI buffer, I thought the Audio buffer was regulating everything. I raised it from 250 to 1000 and the I/O buffers to 512 with great results so far (4 instances of Play including EWHO platinum + some kontakt stuff and Audio tracks)!
     
    You guys were great help, thanks everyone!

    250 is the default but 500 seems to be the sweet spot.

    I thought audio buffer size matters only during playback and never worried to check that while having problems with bounce. You guys seem to imply otherwise.
