Previous Comments: ------------------------------------------------------------------------ [2003-03-26 18:47:28] shawn at rumental dot com afer running file() about a 2000 times with latest snapshot in win2k running apache 1.3.27 latest win32 binary i get this error: Warning: file(e:\test.txt): failed to open stream: Too many open files in e:\program files\apache group\apache\htdocs\test\testfile2.php on line 12 I used handle.exe from sysinternals to view open file handles http://www.sysinternals.com/ntw2k/freeware/handle.shtml and all file handles opened via file() appear to still be open. This is not the case when testing php 422 output from handle.exe: Apache.exe pid: 1640 MAINFRAME\apache 1e4: File E:\test.txt 1e8: File E:\test.txt 210: File E:\test.txt ... etc 214: File E:\test.txt and it goes on for the number of times file() accessed the file.
