sybase11.9.2无法dump
unix环境下，showserver命令显示主、备进程都正常，开始能dump，但过了几个小时后就没法dump，重启sybase后又可以dump操作，但是过了一段时间后又不能备份了，打isql命令也连不上，奉上日志，各位高人能不能帮忙看下：00:00000:00015:2009/09/26 22:30:11.23 kernelnconnect: t_open, Insufficient or invalid memory

起初以为是内存问题，已经更换内存，但还是报kernelnconnect: t_open, Insufficient or invalid memory这个错 是不是内存配置太小了，把sybase 的max memory给大些试试
