Hello, I (tried to) built an embedded Linux system (X86, Linux2.4.3) with thttpd Web Server(2.21b-p17). With it, I call a CGI, which reads a text file from a DiskOnChip.
After severall reads, the system (or user application using Nano-X) slows lineary down. Fast pressing the browsers "reload" button (before the hole file is read) makes the system almost stop. There is no recovery after slowing down at all (maybe after x hours, I didn't test it). Does anybody watched a behavior like this? Is thttpd "eating" memory up after every call (I watched with free() 8-32 Bytes every CGI call)? What is about swapping? Assuming the left free memory is weak, does Linux tries swapping, even with a ramfs (root is packed as zImage, loaded with syslinux in ramfs during the boot process). Can the swaping cause the system slowing down? When I ran the system via NFSRoot, it works stable.... Many thanks for your help, Olaf -----Ursprüngliche Nachricht----- Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]Im Auftrag von Justin Fretwell Gesendet: Mittwoch, 15. Mai 2002 18:43 An: Richard A.
