PostgreSQL 9.0.1上的間歇性Pg.dll崩潰+ Win2k3sp2上的ActivePerl 1007 + Apache 2.2.17

Question

最近我們一直有神祕的，間歇性的Apache崩潰，每天幾次，但沒有模式，關於何時或多久在之間或一天中的什麼時間。

我會升級DBD :: Pg，但是我找不到比我們使用的更新的PPD（2.14.1）。也就是說，自那時以來的變化似乎與我們的使用情況不相關。

Windows事件查看器顯示這一點：

Event Type: Error 
Event Source: Application Error 
Event Category: (100) 
Event ID: 1000 
Date:  2010-11-01 
Time:  9:55:28 AM 
User:  N/A 
Computer: myserver 
Description: 
Faulting application httpd.exe, version 2.2.17.0, faulting module Pg.dll, version 0.0.0.0, fault address 0x0000e8a5. 

所以，我看着在Apache日誌，裏面說：

[Mon Nov 01 09:55:32 2010] [notice] Parent: child process exited with status 3221225477 -- Restarting. 

不是非常有幫助，所以我看着在PostgreSQL的日誌（PG。 DLL是DBD::Pg一部分），他們說：

但除此之外，我不知道至於原因，除了可能的更高的時間（但不是那麼高 - 我們的用戶非常少）服務器負載。

任何想法可能導致這種情況？

Answer 1

間歇性網絡問題可能導致此問題。我嘗試使用運行在VirtualBox上的Turnkey中的psql來運行PostgreSQL中的PostgreSQL，PostgreSQL運行在同一臺服務器上，它有時會導致PostgreSQL線程佔用更多CPU，然後不允許登錄。在Turnkey上安裝PostgreSQL使得停止發生，因此可能在Windows級別存在一個普遍的網絡問題，導致PostgreSQL和Pg​​.dll特別嗆，然後崩潰Apache，因爲DBD :: Pg通過mod_perl持久地加載。
