Member Data Documentation

EnableAgressiveGc

bool ConnectionManager::EnableAgressiveGc = false

static

Enable Agressive Connection Garbage Collection to have resip perform garbage collection on every new connection.

If disabled then garbage collection is only performed if we run out of Fd's

Definition at line 36 of file ConnectionManager.hxx.

MinimumGcAge

uint64_t ConnectionManager::MinimumGcAge = 1

static

connection must have no inbound traffic for greater than this time (in ms) before it is garbage collected

Definition at line 26 of file ConnectionManager.hxx.

MinimumGcHeadroom

uint64_t ConnectionManager::MinimumGcHeadroom = 0

static

If the difference between the number of permitted FDs (reported by periodic calls to getrlimit()) and the number of active stream connections falls below this threshold, the garbage collector will overlook MinimumGcAge and more aggressively close connections.
