Those are equivalent in bash; what led do you make that change and what difference does it make? If you are regularly doing a reload/graceful restart of httpd, various modules can leak memory. thanks for fast response. this redirection was the first thing that was suspicious for us. script hash /bin/sh (not bash) shebang and this type of redirection is not common (>& is used mostly with output redirection by id) i checked that newer apache2 package in debian is using the more common style "2>/dev/null" what is leaking is not ram memory, but disk space. we will follow this issue more and report any informations. Do you have further feedback on the issue? no i have nothing to add. i vote for closing this bug as notabug OK, thanks for getting back to us. |
