solr - socket timeout exception on ubuntu -


we have solr router , shards. appears in jetty log of router when doing faceted search across shards.

org.apache.commons.httpclient.httpmethoddirector executewithretry  info: i/o exception (java.net.socketexception) caught when processing request: connection reset peer: socket write error  org.apache.commons.httpclient.httpmethoddirector executewithretry  info: retrying request

followed exception internal server error. run eighty shards distributed across several servers. router runs on own node.

upd: in httpcommcomponent class of solr sumbits requests shards using httpclient class have noticed following set on multithreadedhttpconnectionmanager: mgr.getparams().setdefaultmaxconnectionsperhost(20);

it seems me little setting 80+ shards.

after more debugging have found out, 1 of requests had size of 4,4mb. default maxpostsize in tomcat6 2mb (http://tomcat.apache.org/tomcat-6.0-doc/config/ajp.html).

changing 10mb has improved situation on solr side.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
