Issue ID: 10190
Summary: Stack space exhaustion on windows due to FD_SETSIZE
Product: OpenLDAP
Version: unspecified
Hardware: All
OS: Windows
Status: UNCONFIRMED
Keywords: needs_review
Severity: normal
Priority: ---
Component: libraries
Assignee: b...@openldap.org
Reporter: varunpa...@ucla.edu
Target Milestone: ---
Setting FD_SETSIZE is only effective on Windows and BSD, and is
currently set to an unreasonable default of 4096. Each fd_set
is initialized with an array of file descriptors of this size;
this allocates 8*4096 bytes on 64-bit machines, which quickly
exhausts the small stack space on Windows.
This patch sets the default to a more reasonable value of 128;
the default value on Windows currently is 64.
