In my APP, there are 50 QWebPages, which loading many URLs without stop, these QWebPages share one QNetworkAccessManager.

After about 300 URLs are loaded by QWebPages, my APP crashed and display following message:
[New Thread 0x5f585940 (LWP 28949)]
QEventDispatcherUNIXPrivate(): Unable to create thread pipe: Too many open files
QEventDispatcherUNIXPrivate(): Can not continue without a thread pipe

I have recorded every QNetworkReply created by QNetworkAccessManager in a replyList, when one QNetworkReply finished, i
remove it from replyList, when my APP crashed, the replyList has only 50 to 100 QNetworkReplys.
