Pipe to quartus_asm broken but process still running, terminating quartus_asm

[Altera_Forum]

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 Info: ******************************************************************* Info: Running Quartus II 64-Bit Assembler  Info: Version 15.0.0 Build 145 04/22/2015 SJ Full Version  Info: Processing started: Mon Mar 14 17:40:52 2016 Info: Command: quartus_asm --read_settings_files=off --write_settings_files=off system -c system Info: Quartus II 64-Bit Assembler was successful. 0 errors, 0 warnings  Info: Peak virtual memory: 7081 megabytes  Info: Processing ended: Mon Mar 14 17:42:34 2016  Info: Elapsed time: 00:01:42  Info: Total CPU time (on all processors): 00:01:41 Error (112002): Pipe to quartus_asm broken but process still running, terminating quartus_asm Error (293007): Current module quartus_asm ended unexpectedly ------------------------------------------------ ERROR: Error(s) found while running an executable.
