Pipe to quartus_asm broken but process still running, terminating quartus_asm

Hi,

I am facing a issue while running a design on QUARTUS 15.0 version.

The error comes after the assembler stage while compiling the design. Following is the log -

Info: Total CPU time (on all processors): 00:13:54

PS - there is enough memory space and OS used is linux.

Any help would be worth.
