Random Crashes with NVFS - need help with locking and protecting app

[G. Kalyana Sundaram]

Hi All,   Our app is crashing randomly with NVFS systems. The app is spanning across multiple segments, running in background. In background mode – the app uses only code from segment 1 and makes calls to libraries. Also we read data from databases in background mode – we use DmQueryRecord, get a handle and lock it till the read is done. We also perform some file writing in background (mainly for logs) – for each write – we open, write and close it immediately.   I read posts regard to the locking application and tried locking Segment 1 and protecting it. But the crashes did not stop.   Should I lock all segments, libraries that are accessed and the databases as well?   I am using DMGetResource (‘code’, 1); I can iterate through 1- N for all segments and after locking I close the database. But how to lock the databases – should I use DmQueryRecord, lock and close the database? – and unlock when my app it not running in background by storing the memhandles in a preference or feature?   Any help with regard to this is appreciated.   Thanks.   Regards, G.
