Removed ndb_3_signal.log to make package smaller

Description: Using hugoLoad I'm inserting data, witch batch size set to 1990. It kills the data with a temporary error. When data node not again started, it eventually kills the other data node(s). (FYI, hugoLoad is a tool in the MySQL source: cd storage/ndb/test/ ; make) How to repeat: CREATE TABLE t1 ( id INT UNSIGNED NOT NULL AUTO_INCREMENT, i1 INT, i2 INT, i3 INT, txt VARCHAR(60), txt2 VARCHAR(60), hugo_counter INT UNSIGNED NOT NULL, PRIMARY KEY (id), UNIQUE KEY (i1), UNIQUE KEY (i3,txt) ) ENGINE=ndbcluster; shell> NDB_CONNECTSTRING=localhost:1406 time ./tools/hugoLoad -r 4000000 -b 1999 -d test t1 batch = 1999 rowsize = 188 -> rows/commit = 2722 |- Inserting records... ERROR: 4031 Node failure caused abort of transaction Status: Temporary error, Classification: Node Recovery error File: HugoTransactions.cpp (Line: 665) Suggested fix: * Don't batch like I did. * Might be a configuration issue? But then again, would be great not to kill data nodes with an NDB API application.
