some more info on this,

I deleted all the old files from the project/&PH& folder as per a technote but still no use,

NOTE: this job completed fine once before this abort, but before that it got failed, since 3 days couple of times it executed fine after changing the values APT_Max_Transport_block and APT_Min_Transport_block values.

any inputs on this issue is appriciated,

thanks.

Have you changed the memory offsets used by DataStage engine?
