没有改为750的时候也是这个错误？

jishuang

把这个值改为默认的，把tomcat的logs和model同级的logs中的日志文件都清了

下次假死的时候把tomcat和model同级的logs发一下

jishuang

并发量是多少？
tomcat\conf\server.xml中配置的maxThreads是多少？

chensl

750啊

jishuang

并发量是多少？

chensl

并发量并不大，同时在线的没超过30人

jishuang

同时在线的没超过30人，那么tomcat中tomcat\conf\server.xml中配置的maxThreads就按平台默认的配置就可以，不需要自己修改

这个不是修改的越大越好

chensl

不设大半天tomcat就假死了，设了一天假死，没有解决办法吗

jishuang

不设大半天tomcat就假死了，假死的报错信息就是Maximum number of threads的问题？

上面有线程报错的原因啊，locked
