Hi Vlad, > Looks like in your environment, writer cannot send buffers greater than > 512, not sure why
yep, I have many directions to look for... It's NaviServer in a chroot, on a SUSE LINUX Enterprise Server 9. I set logmaxlevel to 6 (dev) and I sometimes see lines like: Debug: SockSend: Resource temporarily unavailable Debug: SockSend: Resource temporarily unavailable (...) when the page (with lots of images) gets rendered and I follow some links/images. This is not writer-thread related, but adds to the socket "thing". I'll give the driver.c change a try, thanks. Bernd.
