svn报错 400 Bad Request

MyEclipse中的svn，commit经常报错

Error: Commit failed (details follow): 
Error: At least one property change failed; repository is unchanged 
Error: Server sent unexpected return value (400 Bad Request) in response to PROPPATCH 
Error: request for '/svn/portal/!svn/wrk/... 
Finished!

经网上查询，发现新升级的卡巴斯基可能对其进行隔离限制，关掉卡巴斯基，提交成功。
