I have a program in which I have created 160 threads-- for working on data directed to them respectively and 1 thread-- which holds the data in a map.

All the threads are been created while running the program.

problem:
At times my some threads out of 160 threads are not been able to read the data from map in the data thread.

I tried reducing the Mutex locks but still the problem remains the same.

please help for the same.

What about 159 threads, or 59, or... 4? You've not provided *nearly* enough information to assist with your problem, so at-best all you'll get are wags. – WhozCraig Jul 28 '14 at 08:51

160 threads seems unreasonably many – zoska Jul 28 '14 at 08:56
Why do you want for the 160 threads to read the data? – vz0 Jul 28 '14 at 09:22
i want 160 threads to read as well as do sm operations..there are different operations done by all the 160 threads. – user3769613 Jul 28 '14 at 12:56
