open connections are not closed

Tinyproxy version

Tinyproxy version tinyproxy 1.11.1

Issue

timeout 10 max clients 2500

timeout doesn't kill the open connections, once the open connections reach 2500 the proxy stops working. as mentioned in previous issue https://github.com/tinyproxy/tinyproxy/issues/509 kill and restarting would help but it is impacting the application functionality

Thanks

timeout handling was fixed in 79d0b0fa79249a714cbb1992d597e21adc30b16e. my local tinyproxy has maxclients 100 and is running > 6 months without issues. it could be possible that there is still some cornercase bug regarding the timeout handling, but apparently it is only hit with clients doing something extraordinary. can you provide some testcase client (python script, or whatever) that let's me reproduce this issue ? if not, at least provide some info about the client accessing your proxy.

in other environments it is working fine for me, recently we have upgraded the kubernetes version of the cluster and the instance we have tinyproxy on is not in the cluster but it is an enterprise instance in the same VPC

if the problem happens only in a specific environment (OS, settings, virtualization) it's likely the bug is to be found there. without knowing any details about that environment, including the sort of client accessing the proxy, it's next to impossible to figure out what's going on.

getting this error while doing tinyproxy -d -c tinyproxy.conf ERROR: Syntax error on line 154 Unable to parse config file. Not starting.

would resolving that error help

by seeing the other threads I have tried the following tinyproxy -d -c tinyproxy.conf ERROR: Syntax error on line 154 Unable to parse config file. Not starting.

your problem is the ancient tinyproxy version shipped on that OS. you need to compile latest tinyproxy from source instead.

[DivyaPadakandla]

Can you help me with removing all the old versions on the OS

[DivyaPadakandla]

when I do Tinyproxy version it shows 1.11.1

[DivyaPadakandla]

did you infer that I am on old version from this yum --showduplicate list tinyproxy Loaded plugins: extras_suggestions, langpacks, priorities, update-motd 227 packages excluded due to repository priority protections Installed Packages tinyproxy.x86_64 1.8.3-2.el7 @epel Available Packages tinyproxy.x86_64 1.8.4-2.el7 epel

where can I change the path to direct the config to take the particular version of installed tinyproxy

use yum to uninstall distro's tinyproxy, then use ./configure --prefix=/usr ; make ; sudo make install in tinyproxy source dir to install new tinyproxy into system default path.
