By default, this value is set to 20000, but it may be increased if necessary, following the limitations of the operating system used.

Using environment variable (since build 5.2.762)

Since build 5.2.762, maximum opened files limit can be set using the following environment variable

Code Block
themeRDark
WCS_FD_LIMIT=20000

in setenv.sh file. When updating WCS from previous builds, this variable should be added to setenv.sh manually, for example

Code Block
themeRDark
export WCS_FD_LIMIT=100000

Unlike the webcallserver startup script, the setenv.sh file is not overwritten on subsequent updates, therefore it is not necessary to restore this setting after every update.
