Windchill PDMLink 10.1 M040 中，在自定义代码中调用 wt.occurrence.StandardOccurrenceService.saveUsesOccurrenceAndData(UsesOccurrence occurrence, Vector occurrenceData) 以后方法服务器无响应

已修改: 03-Nov-2015   


适用于

  • Windchill PDMLink 10.1 M040

说明

  • 在自定义代码中调用 wt.occurrence.StandardOccurrenceService.saveUsesOccurrenceAndData(UsesOccurrence occurrence, Vector occurrenceData) 以后方法服务器无响应
  • 执行 jstat -gcutil 可以观察到有问题的方法服务器的 Eden Space 使用率为100%，但是 Survivor Space 和 Old Gen 仍然有很多可用空间。例如
$ jstat -gcutil <pid> 1s
