Hi all,

Please review a small fix for https://bugs.openjdk.java.net/browse/JDK-8049695 webrev: http://cr.openjdk.java.net/~amenkov/shmemlongname/webrevopen/ Root cause of the issue is jbd hungs as a result of the buffer overflow. In the beginning of the shmemBase.c: #define MAXIPCPREFIX 50   /* user-specified or generated name for */ /* shared memory seg and prefix for other IPC */ #define MAXIPCSUFFIX 25   /* suffix to shmem name for other IPC names */ #define MAXIPCNAME   (MAXIPCPREFIX + MAXIPCSUFFIX) buffer (char prefix[]) in function createStream is used to generate base name for mutex/events, so MAXIPCPREFIX is not big enough. --alex
