在WIN环境变量中设置: _JAVA_SR_SIGNUM =12, 若Linux下用 export _JAVA_SR_SIGNUM =12, 基本就可以解决. sun的解释: --posted by: cooper Below is a clipping from Sun on working around JVM crashes under high thread counts in the JVM 1.3 for Linux On Linux, use a larger signal number for hotspot thread suspension/resumption handler. The signal number being used is specified by environment variable _JAVA_SR_SIGNUM. Setting it to a number larger than SIGSEGV (11) will solve the PRoblem. A good number to use is 12, which is SIGUSR2. Using signal 16 to work around the problem might have potential problems. So on tcsh, "setenv _JAVA_SR_SIGNUM 12" can solve the problem.
