What is the test for revocation of probation where there has been a violation of the condition not to associate with convicted felons?

In United States v. Tham, 884 F.2d 1262, 1266 (9th Cir.1989), we held that the district court did not abuse its discretion in revoking probation where there had been a violation of the condition not to associate with convicted felons. We rejected the argument that this condition of probation was merely technical, a violation of which cannot support probation revocation. Id. We ruled in United States v. Hamilton, 708 F.2d 1412, 1415 (9th Cir.1983), that revocation proceeding should not be an automatic reaction to technical or minor violations and that probation revocation should involve facts of opprobrious conduct or antisocial activity.
