Iam trying to upload data into custom object called "Migration" and i have Process on this object in process builder.i tried to insert 350 records into Migration using data loader.If i insert with 10 records,it is not giving any error.If i try to insert 350 into the object,then all the records are getting failed.Not able to figured it out what is happening.Need help,Thanks in advance
The reason behind this is probably - with the limited information you gave - that your batch size on the dataloader is to big causing governor limits to be exceeded.
The process builder can be tricky like that. If you want to do the dataload without making any changes i would change the batch size as Koen Certyn says. You know that it will run with 10 so you can start with that, it would take longer time to do the dataload. The way you change the batch size is by clicking settings and change the Batch size.
