In reply to puranik.sunil@tcs.com:

Please have a look at this thread Argument Passed by Reference cannot be used within fork-join_any/join_none - SystemVerilog - Verification Academy

Basically this a restriction, I wonder if you actually require msg_size to be ref** variable, but I’m not sure what is your requirement.

LRM Section 9.3.2 Parallel Blocks

…Within a fork-join_any or fork-join_none block, it shall be illegal to refer to formal arguments passed by reference other than in the initialization value expressions of variables declared in a block_item_declaration of the fork.
