![]() APAR status Closed as program error. Error description This plugin related problem and it occurs for very large POST data because the plugin currently allocates a large buffer to store thecontent in. If the content is so large that it causes the malloc() to fail we don't handle that correctly and the request fails. A change needs to be made to the plugin so that for large amounts of content we allocate a smaller buffer and read a chunk/write a chunk until all content is successfully passed to the app server.Local fix The workaround may be to send http request to embedded IHS server but for most customers this workaround will not be acceptable.(Most of them use standalone WebServer).Problem summary **************************************************************** * USERS AFFECTED: WebSphere Application Server version 4.0 * * users of the webserver plugins. * **************************************************************** * PROBLEM DESCRIPTION: POST requests with very large request * * content(>70 meg) would fail when being * * sent to the plugin. * **************************************************************** * RECOMMENDATION: * **************************************************************** The plugin would fail to allocate the buffer to read the request content into when content-length was set to a very large value(>70 meg). As a result the request processing would fail.Problem conclusion The plugin was modified so that when the request content is greater than a certain size it will read a chunk and write a chunk until all the content is read.Temporary fix The efix has been provided to the customer and we are awaiting confirmation that it worked.Comments
