Loadrunner：场景运行较长时间后报错：Message id [-17999] was not saved - Auto Log cache is too small to contain the message.

loadrunner运行时间较长后，跑数据过程老是失败，有如下error：

Message id [-17999] was not saved - Auto Log cache is too small to contain the message.

Action.c(58): 20470-byte response body for IMAP Fetch

因为脚本中默认写日志的缓存为1KB，修改该配置为999
